摘要
电动座椅调节就是可以通过电机的控制来调节座椅的前后位置、上下高度、靠背角度,更豪华的还可以调节大腿支撑、腰部支撑等。实用性非常强,可以使自己处于一个相对舒适的驾驶位置。宝马3系F35手动调节的工作方式就是驾驶员本身作为一个施力方,通过手柄放松座椅的锁止机构,之后通过改变身体的座姿和位置来带动座椅移动,最后将锁止机构的手柄放松,将座椅固定在所选择的位置上。
常见的电动座椅的故障存在有:调节异响,无法调节,记忆功能失效等。在结合了宝马3系F35电动座椅控制原理和实际故障情况下,利用宝马专用诊断设备和车间维修工具,设计出了可靠有效的故障诊断树和相应的排故方案。在实际生产中发现,该排故方案可靠有效,对实际生产具有指导意义。
